レイヤー

You can switch between different "layers" offering different views of the same mapping data. Do this by clicking the layers icon (4)

The layer called "Standard" is the default. "Cycle Map", "Transport Map" and "Humanitarian" are alternatives. The styles look quite different. Which is better, is often a matter of personal preference. These views are rendered in different ways (being turned from raw data into a map image), although all of these use Mapnik software. Because the layers are running on different server infrastructure with different set-ups, one layer may be more out-of-date compared to another (recently mapped roads not showing up).

キー

For the “Standard” and “Cycle Map” layers there is a basic key available showing how different types of primitives (mainly roads) on the map are rendered. Click the “i” icon (5) to bring it up. For a more complete key of Standard, see JA:標準タイルレイヤー/キー. For a more complete key of Cycle Map, see [1].

その他のデザイン

Newcomers should also note that it is in the nature of OpenStreetMap that there are many many other designs of maps available elsewhere if the small selection on www.openstreetmap.org don't appeal. They are all based on the same OSM data. A good point to start discovering may be List of OSM-based services.

ノート

In the 'layers' sidebar (4), you can also tick 'notes' to view any notes which people may have placed on the map here. If there are any, you will see markers appear. Click the markers to read the notes.

In the 'layers' sidebar (4), you can also tick 'data' to activate the data browser. This gives you a view of the underlying data, allowing you to select the elements and view their tag data, and editing history. Similar features are also available within the editors (See Editing). This view is read-only. It is a JavaScript interface which requires a powerful up-to-date web browser, but does not require flash support.

There is also an easier data interface: use the query features tool by clicking the ? (11). Then click a spot in the map to see which data elements are at this spot.

copying the URL from your browser's address bar (8) and pasting it, for example, in an e-mail to send. By using (clicking) that URL, the recipient will see the same map as you see (with any optional highlighting you made to show a feature).

短縮リンク

OpenStreetMap supports highly compact short URLs which can be generated from the 'share' panel (6). Short links are great for emailing, tweeting, and otherwise sharing map links in situations where a long URL can cause problems. They redirect to the longer type of the URL described above. Note that these short links are case sensitive and contain I, l and 1. In some fonts these characters can be difficult to distinguish. For more about how the feature works see Shortlink.

Other URL tricks

Note that some URL parameters may not be supported long term. We offer no guarantees.

The parameters mlat and mlon are used to indicate the position of the red marker. Please note that your marker may be outside the shown map part.

The layer URL parameter takes a special Layer Code representing your layer selection. The parameter is optional and if you leave it out, we will default to showing our "standard" map style. See Layer URL parameter for more information.

The "api/0.6" variants return the raw data (suitable for osm editors and software) instead of an html page (suitable for web browsers). This might suite your needs better, and usually works much faster than the html version.

Once you've looked around our maps it's time to zoom in on your neighbourhood and try out that edit button (9). See Editing for more instructions, and also check out http://learnosm.org a nice documentation site for beginning editing.
